During the remainder of the revolution thereof the ring rests upon the unslotted 1 portion of the sleeve and no oil is fed to the t axle. The rotation of the sleeve causes the rotation of the ring 16, so that when the rib 17 sinks into the slot 15 it will bring a fresh 1 supply of oil along with it from the reserl voir 5.

Many modifications may be made in our invention, since the slotted sleeve may be made an integral part of the wheel, the lib 17 may be omitted or modified in cross-section, the ring 16 may be exchanged for a chain or other o.l-feeding device, and the details described may be otherwise varied or be in some cases omitted without departing from the spirit of our invention.

We claim- 1. In a rotary device, a hollow hub serving as an oilreceptacle, an oiling-ring therein, and means for causing the said ring to feed oil to the axle intermittently.

2. In a rotary device, a hollow hub serving as an oil-receptacle, a sleeve surrounding the axle and carried by the hub, and an o'.ling

ring encircling said sleeve, said sleeve having a portion arrange :l to lift said ring out of contact with the axle intermittently.

3. In a rotary device, a hollow rotatable hub serving as an oil-receptacle, a sleeve ent circling the axle and carried by said hub, said sleeve having a peripheral slot for a portion of its circumference, and an oiling ring adapted to feed oil through said slot curing a portion of the revolution of the wheel. a

4. In a rotary device, a hollow hub serving as an oil-receptacle, a sleeve encircling the axle but out of contact therewith and carried by said hub, and an oilin g-ring encircling said sleeve, there being a slot in the sleeve for causing the ring to feed oil to the axle intermittently.

5. In a rotary device, a hollow rotatable hub serving as an oil-receptacle, and an oiling-ring therein encircling the axle, there being a slot for a portion only of the circumference of the wall between the oil-receptacle and the axle, whereby the a portion of the revolution of the wheel feed oil through said slot to the axle.

6. In a rotary device, a hollow hub serving as an oilreservoir and having a slot through the inner wall thereof, and an oiling-rin having a flange adapted to extend through said slot and supply the bearing with oil.
